你将一个气球带上月球,月球的大气气压是0 , 如果气温不变的情况下, 气球的体积会有什么变化呢?You take the balloon to the moon, where the atmospheric pressure is zero.(Assume that the temperature remains the same.) what might happen to the size of the balloon?.(use the kinetic molecular theory to explain)

答
气球里面的气体体积会膨胀,从而涨破气球,这道理与氢气球飞上太空边缘会膨胀爆炸类似. 气体总是朝气压低的地方去,就是这个道理
答
根据分子动力论中的气态方程(pV=nRT)题目条件及可知,因为T(温度,单位:开尔文)不变,n、R均为常数,所以等式右边恒为定值,又因为等式左边p减小(月球上大气压小于地球),故V(气球体积)变大.根据题意,p一直减小至...
